Why was Moteino Leo discontinued?

I barely see any mention of it in the forum archive.  Was it hard to run at as low a low power as the atmega328p or something?  The ATMega32u4 chip does seem to have some nice features that would be nice to have (16 bit timer3, 200x differential voltage amplifier, higher reference voltage, built-in USB support, etc.)

Flakyness, bloated usb bootloader, harder package (well they have a TQFP too i guess). I was stretching it a bit too much. I think the 1284p Moteino is a much better success than the 32u4.
I don't even know about the low power.
